How much water does it take for a toddler to drown?

Very little. A young child can drown in as little as an inch or two of water, and it can happen quickly and silently. That includes buckets, wading pools, coolers, pet bowls, and the bathtub. Empty open containers right after use, and stay within arm's length of your toddler near any water.

Are floaties or water wings enough to keep my toddler safe in the pool?

No. Floaties, water wings, and inflatable toys can deflate or slip off, and they do not prevent drowning. They are not safety devices. They can also give a false sense of security that leads adults to relax supervision. Use a properly fitted life jacket when flotation is needed, and keep an adult within arm's reach.

What SPF sunscreen should I use on my toddler, and how often do I reapply?

Use a broad-spectrum sunscreen with an SPF of at least 15; SPF 15 or 30 is fine for most children. Reapply every 2 hours, and after swimming, sweating, or drying off. For babies under 6 months, keep them out of direct sun and use sunscreen only on small exposed areas when shade and clothing are not available.

Can I use bug spray with DEET on my toddler?

Yes, with limits. The AAP supports DEET between 10% and 30% for children, but not on infants under 2 months. A 10% product lasts about 2 hours; 30% lasts about 5 hours. Do not apply it to your toddler's hands, avoid combination sunscreen-repellent products, and wash it off with soap and water once indoors. Avoid oil of lemon eucalyptus on children under 3 years.

How fast does a parked car get dangerous for a child?

Fast. The inside of a car can become dangerously hot in a short amount of time, even with the windows open, so never leave a child alone in a vehicle, even briefly. Heatstroke can follow. Always check the back seat before walking away, and keep the car locked so a child cannot climb in unnoticed.

Toddler Summer Safety: Water, Heat, and Sun

Drowning is the leading cause of death in children ages 1 to 4. It happens in seconds, and it is often silent.

Summer changes the risks your toddler faces. The biggest one is water. A child can drown in an inch or two of water, without splashing or calling out. This guide starts with drowning prevention, then covers sun, heat, hot cars, bug bites, and hot playground surfaces. Read the water section first. The rest matters too, but water is where seconds count.

Start here: water comes first

Drowning is the leading cause of death in children ages 1 to 4. It is fast and quiet. There is no scream and no struggle you can hear from across the yard. Most of these drownings do not happen during planned swim time. According to the AAP, 69% of drownings in children age 4 and younger happened during non-swim times, when no one expected the child to reach water. That is why the layers below are not optional extras. They are how you keep a normal afternoon from becoming an emergency.

Drowning prevention: the layers that work

Touch supervision. Stay within arm's length of your toddler in or near water, at bath time and swim time. Close enough to reach out and grab.
Designate a Water Watcher. One adult watches the water with no phone, no book, no alcohol. Hand the job off out loud when you rotate, every 15 to 20 minutes, so it is never 'everyone's job,' which means no one's.
Four-sided pool fencing. The fence should be at least 4 feet high, completely separate the pool from the house and the rest of the yard, and have a self-closing, self-latching gate that opens away from the pool. Openings should be less than 4 inches wide, and the latch should sit at least 54 inches from the ground, above a toddler's reach.
No reliance on inflatable toys. Floaties, water wings, and inflatable rings can deflate or slip off. They do not prevent drowning and are not safety devices. Use a properly fitted life jacket when one is needed.
Empty containers after every use. Buckets, wading pools, coolers, and pet bowls hold enough water to drown a toddler. Empty and store them upside down.
Do not let your toddler bathe alone. Children should not be left alone in the bath until they are at least 6 years old.
Learn CPR. Your skills could save a life in the minutes before paramedics arrive.

Sunscreen and sun protection by age

Under 6 months

Keep babies younger than 6 months out of direct sunlight. Find shade under a tree, an umbrella, or the stroller canopy.
Rely on shade and clothing. If shade and protective clothing are not available, apply a small amount of sunscreen to exposed areas like the face and backs of the hands.

Most sun exposure at this age can be managed with a stroller canopy, a hat, and timing.

6 months and older

Use a broad-spectrum sunscreen with an SPF of at least 15. SPF 15 or 30 is fine for most children.
Apply to all exposed skin, with care around the eyes. For sensitive spots like the nose, cheeks, ears, and shoulders, try a zinc oxide or titanium dioxide formula.
Reapply every 2 hours, and after swimming, sweating, or drying off.
Add a hat with a 3-inch all-around brim to shield the face, ears, and back of the neck, plus youth sunglasses with at least 99% UV protection.
Limit sun exposure between 10:00 a.m. and 4:00 p.m., when UV rays are strongest.

You do not have to keep your toddler indoors all day. Shade, a hat, and reapplied sunscreen cover most outings.

Bug repellent: what to use at what age

Repellent	Age limit	How long it lasts
DEET 10%	Not on infants under 2 months	About 2 hours
DEET 30%	Not on infants under 2 months	About 5 hours
Oil of lemon eucalyptus / PMD	Not on children under 3 years	Varies by product
Picaridin 5%	2 months and older	3 to 4 hours

Bug repellent: how to apply it safely

Use DEET between 10% and 30%. Higher percentages last longer but are not stronger. Match the concentration to time outdoors.
Do not apply repellent to your toddler's hands. They put their hands in their mouth and eyes.
Do not use combination sunscreen-and-repellent products. Sunscreen needs frequent reapplication; repellent does not.
Wash your child's skin with soap and water once they are back indoors.
Apply sparingly to a young child, and avoid cuts and irritated skin.

Heat, hydration, and hot playgrounds

Offer water frequently and keep it within reach during play, even before they ask. A heat index at or above 90°F is a significant risk; outdoor activity becomes especially dangerous when the heat index is greater than 105°F.
Watch for dehydration: fewer wet diapers, no urination for an extended period, dry mouth, or no tears when crying.
Check playground surfaces before your toddler touches them. Metal slides, dark rubber matting, and asphalt can get hot enough to burn skin in direct sun. Press your own hand flat on the surface for a few seconds first.
Dress your toddler in light-colored, loose, cool clothing, and take indoor or shaded breaks during peak heat.

Hot cars and heatstroke: call 911

Call your pediatrician

Extreme tiredness or is hard to wake
A severe headache, intense thirst, or muscle cramps
Nausea or vomiting after heat or sun exposure
No urination for an extended period, or far fewer wet diapers than usual
Heavy sweating with cold, pale, clammy skin (signs of heat exhaustion)
Any near-drowning event, even if the child seems fine afterward and is breathing normally
